BUTTON.'

=SPEGIISIGAJZIIION' forming part of Letters Patent No; 288,053, dated November 6, 1883, Application ined .rune n, isea (No maar) To @ZZ whom it may concern.-

Be it known that I, JOHN H. GREGORY, of the city and county of Providence, 'and State of Rhode Island, have invented a new and useful Improvement in Buttons, and I do hereby declare that the following specification, taken in connectioniwith the accompanying drawings, forming a part of the same, is a full, clear, and exact description thereof.

rIhis invention relates to a button which is particularly adapted for use upon shoes and gloves 5 and it consists in a button composed of a back having an attached shank which is 'screwupon the shank, and a head adapted tovbe screwed upon the shank, and thereby firmly to clamp the material to which the button is applied between the button-back and -the iiange on the sleeve, as will hereinafter ap pear.

Referring to the drawings, Figure 1 repre'- sents a side view of the button applied to a piece oi' leather or other material. Fig. 2 shows a vertical section of the same. Fig. 3 represents in perspective the parts of the button detached from each other.

As shown in the several figures, the button is composed of 'a back, A, to which is secured a screw-thread, a sleeve, C, provided with a flange, c, of about the size of the back A, and a head, D, which is adapted to be screwed upon the shank B.

In applying the button, the shank B is passed through aperforation inthe material, as shown the shank, and the head D is screwed down upon the end of the sleeve C, thereby causing the material to be firmly clamped between the back A and the ilange c, both of which are intended to be sufficiently extensive to furnish a broad hearing on the material, and thereby securely hold the button in place.

be screwed down upon the sleeve C sufficiently hard to prevent the parts becoming detached accidentally during use, and when the shoe or glove becomes worn thcbutton may be re` `sleeve C re-enforces and strengthens the iiange or washer c, of which it forms a part, and pressure is .distributed over the entire surface of the flange, which is not liable to be cupped, as would be the case with Monks7 construction. It also differs from the last two patents inentioned in that the flange or washer c is not liable to be rotated in contact with the fabric to which the button is applied, and said fabric thereby abraded or damaged.

What I claim, and desire to secure by Let ters Patent, isy The button herein described, consisting of a back, A, having an attached.screw-threaded shank, B, a flanged sleeve, C o, loosely mounted upon said shank, and a head adapted to be screwed upon ,the shank, substantially as and for the purposes specified.
